The results we achieved reflect positive pricing fundamentals within the industry and our continued focus on internalizing a greater volume of the waste we collect into our landfills. Our goal is to continue to improve our operating margins by leveraging our asset base and overhead structure as we seek to add more customers along existing routes. We believe our network of hauling operations, transfer stations and landfills located in strategic markets in six southeastern states are well positioned to benefit from projected population and economic growth in 2007." Waste Industries also provided its outlook for 2007. The Company's outlook excludes the impact of any additional acquisitions. The outlook provided below is forward-looking, and actual results may differ materially depending on various risks and uncertainties, including those detailed at the end of this release and in our periodic SEC filings.

     -- Revenue is estimated in a range of $335 million to $337 million.
        This assumes internal growth in a range between 2.5% and 3.0%,
        excluding the impact of commodities.  Growth is primarily from
        price, with relatively flat volume.
     -- Selling, general and administrative expense is estimated at 13.4% to
        13.6% of revenue, subject to quarterly fluctuations.
     -- Depreciation and amortization is estimated at 10.0% to 10.2% of
        revenue, subject to quarterly fluctuations.
     -- Operating income is estimated at 12.5% to 13.0% of revenue, subject
        to quarterly fluctuations.
     -- Net interest expense is estimated at approximately $10.5 to $10.8
        million.
     -- Effective income tax rate is expected to be 39.3%, subject to
        quarterly fluctuations.
     -- Net cash provided by operating activities is estimated to be
        approximately 15% of revenue, subject to quarterly fluctuations.
     -- Capital expenditures are estimated to be approximately $39 million,
        of which approximately $12 million relates to the construction
        of and equipment for the operation of the proposed Wake County, NC
        landfill.

* Operating income before depreciation, amortization and accretion and free cash flow are considered non-GAAP financial measures. The Company defines free cash flow as cash flows from operating activities less capital expenditures plus proceeds from the sale of property and equipment and other assets. Operating income before depreciation, amortization and accretion and free cash flow do not represent, and should not be considered as, an alternative to net income or cash flows from operating, investing and financing activities, each as determined in accordance with GAAP. The Company's definitions of operating income before depreciation, amortization and accretion and free cash flow might not be comparable to similarly titled measures reported by other companies. The Company believes that the presentation of operating income before depreciation, amortization and accretion is useful to investors because it provides important information of the Company's operating performance exclusive of certain non-cash costs. The Company has included information concerning free cash flow because it believes it provides additional information for determining its ability to meet debt service requirements and that this measure is an indicator upon which the Company, its lenders and some investors assess its financial performance and its capacity to service debt. The Company therefore interprets free cash flow trends as a measure of its liquidity.
